Specification forming part of Letters Patent No. 142,465, dated September 2, 1673; application filed March 17, 1873.

To all whom it may concern:

Be it known that I, JOHN HINZEY, of the city of Peoria, in the county of Peoria and in the State of Illinois, have invented an Improvement in Machines for Scouring or Smutting and Separating Grain; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the annexed drawings, making a part of this specification, in which like letters of reference refer to like parts, and in which Figure 1 represents an exterior elevation of ope-half of the machine and a general section elevation of the other half; Fig. 2, a horizontal section through Fig. 1 along dotted lines 1 1; Fig. 3, vertical section of tail Z of suction-spoutP; Fig. 4, plan of suction-spout P P P Q, the top board or roof being removed, showing its position on the fan-box N;

by a fan or fans on the arms which carry the revolving beating-rods before mentioned into an exterior chamber, whence a suction-fan attached to the machine draws it away, at the same time extracting the light grain, by a suction-spout, from a spout at the lower end of the cleaning-cylinder. The beaters or revolving rods are mounted on radiating arms carried by a central vertical revolving shaft, and

extend nearly to the inclosing-cylinder. The fans for blowing the smut, &c., out of the cyl inder fill up the space between the rods and the shaft, and between the top and bottom plates of the cylinder.

--One of the forms in which I construct this machine is as follows: In the drawing, A A represent four upright post-s rising from the sills E E, and braced at the top by the crosspiece B B--i. 6., the pairs on each side parallel with the suction-box P. D D, &c., are

lower horizontal braces under those at B B, and which support the cleaningcylinder G. E E are horizontal sills or beams, in which the posts A A, &c., are mortised. F is a horizontal metal plate resting upon the braces D D, &c., and'forms the bottom inclosure of the cylinder G, and on which the latter rests, and on which the cylinder is confined by pins or other stops projecting from the plate. A passage, W, opens through this plate into a spout, it, below which enters the suction-passage P G, the cleaning cylinder, resting upon plate F, composed of a series of vertical steel or iron rods or staves of a round, oval, or similar figure in section, and about three fourths of an inch in diameter and one-fourth inch in thickness when made oval or semicircular. The convex surfaces of each are presented toward the interior of the cylinder, and a vertical opening is left between each of about onesixteenth of an inch for the passage of air, smut, &c., outward to the fan 0, as shown by the arrows, Figs. 1 and 2. The rods are collectively confined at each end in a groove in the face of a metal ring, g g, (one forming the top, the other the base, of the cylinder G,) which are braced together by means of rods passing through lugs projecting from the rings, and filled with screws and nuts. The ends of the rods are flattened to prevent their contact along their edges where the draft is required to pass. This cylinder, in a large machine, is composed of several cylinders like the above, placed end to end to obtain the necessary height. The cylinder is closed above by a second plate,m, which rests upon the upper ring g, and is perforated at a a for the inward flow of air to the cylinder, around the center, and on its margin, beyond the ring, by segmental openings 41 v, for currents of air to the fan 0 above. It has also a passage, a, for grain into the cylinder. (See Fig. 5.) H I is a rotating cleaner within the cylinder Gr, set upon the vertical shaft K, and composed of six or more radial curved horizontal arms, h h, (see Fig. 2,) near the top of cylinder, and a similar set near the bottom of the latter, perforated to receive the several vertical beatingrods H H, which may be each round in sec tion and extend from top to bottom of cylinsage I.

2 me ses der, or nearly so, and at similar distances apart as those composing the latter. Each row of rods commences near the inner face of the cylinder and continues up to the edge of the fan g on such arms as carry a fan. There are three fans, q q q, around the shaft K, one fan to each alternate arm h in such machines as carry six heaters, and four fans, g, &c., to machines of eight boaters. I I are circular plates, from which radiate the arms which carry the rods, firmly secured to the shaft K. The spaces inclosed between these plates and the rods H and shaft K are filled in each alternate arm by the fans g, which act also as braces between the plates I I. K is a central driving-shaft stepped in the lower end of the machine, where it carries the drivingpulley L. Within the cylinder G it carries the beater H I, &c., and above this the fan 0. M is a circular case resting upon the plate 172 of the cylinder, and which sustains the fan-box N. An opening, a, or spout passes through one side to admit grain into the cylinder; N, the fan-box, of similar diameter to case M and cylinderG, and rests upon the case M, having a central opening, b, above and below, and a spout, k, for discharge of smut, 85c. O, the fan; 1?, air-suction box, extending across the top of the fan-box, and divided horizontally into upper and lower passages by a horizontal division, which terminates in a vertical divission, 0, in a dependent spout, Z, below which is a transverse division, 8. Each passage here terminates with a pendent draft-door, f f. The upper part of the box P is divided by a vertical partition. One of the upper parallel passages, P is an extension of the vertical pas- (See Fig. 4.) That at P is parallel with the latter, and is entered on the side of the passage Q, and is closed at that end next to the vertical suction spout P and can be closed at the other end by a valve, y, thence continuing downward with the partition 0. Q is an upward suction spout from the grainhopper 23 into suction-passage P R is an airsuction entrance around the hopper t. S S, &c., are casings, closing the cylinder from air except by a slit, m, beneath each.

The operation of this machine is as follows: The shaft K being set in motion, the heaters H h H h and fans q q are whirled around at six hundred revolutions per minute simultaneously with the fan 0 on upper end of shaft.

Grain is admitted through the hopper it into the opening a in the plate m, where it is caught by the arms or beaters H h, &c., and driven forward between them and the cylinder 4 rods, well scoured in the passage to fall onto plate I, whence the fans sweep it into the hole to in said plate, whence through spout n it meets the ascending air in spout P, which carries away the screenings. Smut, &c., is carried out of the cylinder Gr between the rods by the upward draft through the slits a; m, 850., under the casing S S, (induced by the fan 0,) through the segmental openings o o in the upper plate m into the fan-box N, where it is ejected through the spout 70. In the meantime the draft up the vertical suction-passage I carries up the light grain and screenings issuing from the spout n with the good or heavy grain; thence along the horizontal passage P and downward hence past the division-board 6, out at the spout Z through the pendent doors or air-traps f f. The air-current continues its course under the board 0, back through the passage P opening I), where it and its dust is expelled in the usual manner through a spout, 70, from the fan.

i/Vhat I claim as my invention is- 1. The combination of the cylinder G, plates F m, shaft K, arms 71/ h, fans q q, rods H H, arranged to operate with the fan box N, fan 0, separating or blast box P P P P Q Z, substantially as described.

2. The combination and arrangement of the cylinder G, rings 9 9 connected by lugs and bracerods, the lower plate F, grain-openin g 10, the upper plate at perforated for admission of air, grain-passage a, shaft K, fan 0, fanbox N, casing M between the fan-box and plate m, blast-box I? P I P Q, airdraft It, hopper t, spout Z, pendent doors ff, frame A A B B D I) D, casings S S, air-passages x w, as described.

In testimony that I claim the foregoing machine for scouring and separating grain, I have hereunto set my hand this 11th day of March, A. D. 1873.

JOHN HINZEY.
